14.125 Flash Memory and Solid State Drives (SSDs)

My book "Patterns in Data Management" is now available both as an ebook or a print book (with color graphics!). See: http://amzn.to/1Ts3rwx This book is not a standard textbook on database techniques. This book was written extending and complementing preexisting educational videos (including this one). What are the major properties of flash devices? What is an SSD? What is the major differentiator over hard disks w.r.t. performance? In an SSD, what are blocks and superblocks? What does this mean for write operations? What is write amplification? How would this affect the storage layer of a database system? Why trim? What is the job of the SSD controller? How does it relate to RAID? How does it relate to volatile memory? Which sequential bandwidth can we expect these days? And which random access time? Video for my inverted classroom "Database Systems".
